'1 Claim. (Cl. 108-7) This invention relates to improvements in 'a stripshingle, and particularly to a strip-shingle of flexible roofing material, such as 'asphalt roofing, which strips, when laid in courses with like strips, will simulate the appearance of roof covering formed with square-butt shingles.

Among the objects of my invention are to provide la twin square-tab strip-shingle, one lower corner of which will interlock with a lower corner of an adjacent strip of the same row, when laid, so as to hold the butts or tabs down and thus increase the wind resistance of the strips.

Other objects are to provide strip-shingles of the interlocking square-butt type that are easy to apply, that can be conveniently cut from a sheet of roofing material with little waste, that are very economical of material in that they aiford a covering of at least two thicknesses of material substantially throughout the roof deck 'with use of only approximately two hundred square feet of material per square of roof surface.

Having reference to the drawings and the following description of the invention, it will be seen that the present improved strip-shingle offers marked advantages over any of those previously devised.

In the following drawings:

Fig. 1 is a plan view of a twin square-tab strip-shingle embodying a preferred form of the invention;

Fig. 2 is a fragmentary detailed plan view showing the manner in which the ends of two adjacent stripshingles of a course are interlocked;

Fig. 3 is a plan view showing a manner of cutting the strip-shingles from a vsheet of roofing material with little waste;

Fig. 4 is a plan view showing a plurality of the stripshingles applied in courses;

Fig. 5 is a plan view of a modified form of the stripshingle;

Fig. 6 is a view showing the modified 'form of the strip-shingle as cut from a sheet of roofing material;

Fig. 7 is a plan view showing a plurality of the stripshingles of the modified form as applied in courses; and,

Fig. 8 is an enlarged fragmentary view of the manner of Cutting the portions that constitute the interlocking ends of the shingles.

The strip-shingle in its preferred form, shown in Figs. l-4, has a substantially rectangular body 10 having parallel straight upper and lower edges 11-12, a straight Vertical end edge 13 at one side and a zg-zag end edge 14 at the other side. The lower portion of said zig-zag edge forms a locking tab 15 at the lower left-hand corner of the body, which tab is complementary in Shape to the recess or cut-out 16 at the upper corner of said side.

On reference to Fig. 3, it will be seen that the form of the two side edges of the shingle is such that a plurality of the shingles may be cut from a sheet of roofing material with alternate strip-shingles of each row re- Z,910,0 1 9 Patented Oct. 27, 1959 'ICC versed in position, as indicated by the characters 10A and 10B in that figure of the drawings.

Two slots 17 and 17' are cut inwardly from the lower edge 12 of the strip-shingle which slots, in the form shown, terminate at their inner ends in oblique edges 18 and 18', respectively. The upper ends of the oblique edges 18 and 18' are in horizontal alignment with the corner 19 of the locking tab 15. Instead of having the slots 17-17' terminate in oblique edges, they may terminate .in horizontal edges. However, to secure better interlockment when the strip-shingles are laid, it is preferred that the upper edge, 'at least of the slot 17, should be an oblique line. In that case, for the sake of uniformity of appearance, the upper edge of the other slot 17' will be formed of a corresponding oblique line. Ex-

.. tending upwardly from the inner ends of the slots 17-17' are oblong areas 20-20' of a darker color than the rest of the surface of the strip-shingle. These areas, together with the cut-outs 17-17', simulate the slots of ordinary square-butt strips and extend upwardly to the ,i full distance that the butt or square-tab portions 21 of the strip are designed to be exposed when laid. The upper horizontal ends of the dark, slot-simulating areas serve as guides for lapping the lower edges of the strips of the next course. If desired, the darkened areas may be omitted, in which case other guiding means may be provided 'for lapping the strips of the succeeding course.

In laying the shingles of each course, the locking tab 15 of one shingle is inserted in the slot 17 of an adjacent shingle of the same row in position that the corner 19 of the tab will engage the corner 22 of the slot. It will be seen that in this manner the two squarebutt portions 21 of each strip-shingle are securely locked down, thus increasing their resistance to being raised by wind. When the shingles are laid in interlocked relation, they are each secured to the roof by three nails, one of which, 23, is dirven into the shingle above the upper end of 'the simulated slot 20', a second, 24, in the lower right hand corner of the shingle, and a third, 25, is driven through the overlapping side edge portion of the adjacent shingle of the same course to penetrate through the two shingles. The heads of the nails so located are covered by the over-lapping butt-portions of the strip-shingles of the succeeeding course, as will be seen on reference to Fig. 4.

The modified form of my improved strip-shingle shown in Fig. 5 dilfers in vform from the strip previously described in that it has parallel straight Vertical side edges 26 and 27 of which the left-hand edge 26 terminates at its lower end in a locking tab 28, and the right-hand edge 27 in a recess 29 complementary in shape to the locking tab 28. Shingle strips of this modified form may be cut, as shown in Fig. 6, all in one direction, that is, without necessity of reversing alternate ones, as in cutting strips of the form first described.

As seen in Figs. 7 and 8, the tab 28 and recess 29 are formed by cutting a Vertical line 30 inward from the lower edge of the strip, which line terminates at its upper end in an upwardly inclined line 31, then descends downwardly in a Vertical line 32, upwardly in a slanting line 33, and downwardly in an oppositely directed slanting line 34. The lines 33-34 may be connected at the top by a curved line. The line 34 forms a locking corner 35 with the Vertical edge portion 27. Preferably, the hatched area 36 is cut out to 'form a horizontal line 37 on the upper edge of tab 28, or optionally said area may be left intact as a projection of the tab. In either case, cutting the strip in this manner provides a slot 38 adjacent the right-hand edge 27 and above the recess 29, as seen in Fig. 5.

A dark slot-simulating area 39 extends upwardly from 3 the edge 31 of the recess 29 to the extent to which the shingle-tab 21 is to be exposed when the strips are lad. A slot 40 is cut inwardly from the lower edge of the strip-shingle and preferably terminates at its upper end in an oblique edge 41 of the same angularity as the edge 31. Extending upwardly from the edge 41 is a dark' slot-simulating area 42 corresponding to the area 38.

When the shingles are laid as shown in Fig. 7, the tab 28 of one shingle of a course is inserted into the slot 38 at the other end of the immediately preceding stripshingle of the same course, in which position the locking corner 35 of the tab will engage in the corner 43 of the slot.

The shingles of the modified form are nailed in a manner similar to that described in connection with the preferred form of strip-shingle.

While my improved strip-shingle has been defined With respect to the two illustrated embodiments, it is to be understood that modifications and variations in those two forms may be made without departing essentially from the scope and spirit of the invention as set forth in the claim.

What I claim is:

An interlocking shingle adapted to be laid in courses with like shingles to simulate the appearance of squarebutt shingles, said shingle comprsing a body having side edges, parallel straight upper and lower edges, a locking tab projecting laterally from one side edge at a lower corner of the body, a parallel-sded slot extending inwardly from the lower edge adjacent the other side and parallel to said other side, a second slot extending inwardly from the lower edge, said second slot vbeing intermediate to said first-mentioned slot and the side edge having said tab, said first-mentioned slot having an upwardly inclined top edge formnig an acute angle with thev side edge of said slot remote from the tab, the tab having an upper edge downwardly inclined towards and forming an acute angle with the proximate side edge, the acute angle formed by the upper edge of the tab interlockng with the acute angle at the top of said first-mentioned slot of the preceding shingle of the same course when the shingles are laid.
